The National Parents Council has now called on Facebook to impose stricter privacy measures following images of young people being intimate.

They criticized the practice and called for "uploading and tagging process to be more strictly controlled".

"What we're seeing here is an invasion of young peoples' privacy. People are inadvertently having pictures taken of them and uploaded on the Internet which can be quite embarrassing," according to spokesperson Jackie Callaghan told the Evening Herald.

"There is a risk of this spiralling out of control. It is a dangerous and unwelcome practice on a lot of levels," she added.
